SEESAW AND ROTARY SWING.

Specification of Letters Patent.

latented Feb. 25 1908.

Application filed October 8. 1906- Serial No. 337.959.

T 0 all whom it may concern:

Be it known that I, ISAAC S. WoonwAno, a resident of Wichita, in thecounty of Sedgwick and State of Kansas, have invented certain new anduseful Improvements in Seesaw and Rotary Swings; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to see-saw and rotary swing.

The. object is to produce a simple inexpensive and durable machineeliminating all dangerous features.

To the accomplishment of these objects and others subordinate thereto,the preferred embodiment of my invention comprehends the constructionand arrangements of parts to be hereinafter described, illustrated inthe accompanying drawings and succintly defined in the appended claims.

In the drawings Figure 1, is a perspective view of a swing embodying myinvention. Fig. 2, a vertical section of thepedestal and swivel. Fig. 3,a toothed disk. Fig. 1, a dog. Fig. 5, the method of joining bars 2 and2 together.

1, designates a pedestal on which is mounted a swivel and bars 2, 2 and3. This pedestal is preferably cast iron and is flared out at the lowerend to provide against toppling over, is circular in form and theunderside thereof is provided with a recess 4, the top end of saidpedestal is approximately the same shape as the lower end, the recessextending down further and progressively diminishing and abruptlyterminating at 4. The top of this recess has annular indents 5 and 6.These indents are for reception of ball bearings 7. I provide a castdisk 9, about one half inch thick, with a round opening 11, in thecenter and an annular flange 12, nearthe perimeter, and on top of thesaid flange are teeth. 10. A cast swivel 13, having indents on theperiphery thereof which are to engage the balls 7, when placed withinthe pedestal 1. This swivel progressively diminishes incontour from theballs down, the free end being provided with a countersink 15, which isfor the reception of a ball 1.6. The top end of the said swivel isbifurcated to receive the bars 2, 2 and 3, and are pierced to receivethe bolts 17, and 18, on these bolts bars 2, 2 and 3 are pivotallysecured as seen in Fig. 1. A dog 19, is made of spring steel and has anindent 20, in one end, the other end 21, is flattened out and has around opening 22, therein, to receive the bolt 23. These dogs areslightly curved. to provide resiliency under concussion. The object ofthe aforesaid indents is to permit the dogs to straddle the flange 12,and teeth 10. The bars 2, and 2 are cut away and joined together as seenat A, Fig. 5. The bar 3, is somewhat longer than the combined length ofbars 2, and 2 which is for the reception of the seats 24, which aresecured. to the bar by screws C. On either side of the free ends'of thebars are battens 25, and are pivotally secured thereto by the bolts 26,and rods 27. Holes 28, and 29, are made for the purpose of adjustment.The object of curving in the bars is to give the free end of the battensa reciprocal movement which is helpful to the riders in operating themachine. The free ends of these battens are pierced for the reception ofthe round rods 30, which rod is for the rider to hold on to. The roundrods 27, serve the double purpose of pivoting the battens to the barsand the riders torest their feet upon. To the bars 2, and 2 arepivotally secured by means of bolts'23, dogs 19. When a rotativemovement is not desired by the riders the dogs 19, can be dis engagedfrom the teeth 10, and made pendent from the bars.

Having described the details of construction of my machine I willnow'describe the assembling and operation thereof.

The disk is placed on the pedestal and secured thereto by the bolts 8. Abolt 16, is dropped down in'the bottom of the recess 4", and the bolts7, are placed in the indents 5, and 6, and the swivel 13, is then placedin the pedestal as seen in Fig. 2. The bars are mounted on theswivel ashereinbefore described, the dogs bolted to the bars and placed inengagement with the teeth 10. When two persons mount the machine andbegin to move the free ends of the bars up and down it will be seen whenthe dogs engage with the teeth 10, the swing will be given a rotarymovement as well as u and down. By reference to Fig. 2, it Wlll be seenthe lower tier of bolts 7, and bolt 16, support the weight of the swivelthe bars and the riders while the upper tiers support the swivellaterally.

Having described the construction of my machine what I claim and wish tosecure by Letters Patent is In a see-saw and rotary swing, a pedestalbars said dogs having a detentin one end, an having interior recesses, aplurality of de- I annular disk with a flange haying teeth thereon, asset forth.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
